Hello
It's a great contest that you have, absolutely challanging question that we programmers appreciate. However for this type of algorithm creation questions, I think we shall need a couple of sample data files.
Have you provided the data files somewhere that I have missed out? The only sample data that I found was on the main contests page, that too the data was trivial and any primitive alogorithm could easily crack that.
We need complicated stuff here so that we can build a good algo.
Thanks!
